When will the Twitterverse learn that tragedy is no joking matter? Make light of death and destruction and you’ll likely face the same professional fate as Russian Ekaterina Solovyeva, who lost her job as an Aeroflot stewardess over a tweet about a plane crash.

“Huh? Did a Superjet crash?” she tweeted. “Hahaha! This aircraft sucks, it’s a pity it wasn’t in Aeroflot, that would be one less.” The crash reportedly killed all 45 people on board the Sukhoi Superjet 100.
